For each problem students will write out all steps of hypothesis testing including populations, hypotheses, cutoff scores, and all relevant calculations. A psychologist has developed a standardized test for measuring the vocabulary skills of 4-year-old children. The scores on the test form a normal distribution with μ = 60 and σ = 10. A researcher would like to use this test to investigate the idea that children who grow up with no siblings develop vocabulary skills at a different rate...
